A Camden Haven resident says he would like the NSW Department of Primary Industries (DPI) to increase surveillance of known abalone locations after he came across an illegal haul.&nbsp; Scott Graham said he found&nbsp;about 40 shells of abalone on Spring Creek Road, Bonny Hills.&nbsp; Scott believes they&nbsp;would have been taken from the rocks at Bonny Hills, as he said this is where they can be found in the region.&nbsp; Scott said majority of the abalone he found was undersize.&nbsp; The legal minimum length is 11.7cm and Scott said some of the&nbsp;shells found were not even nine centimetres&nbsp;long. "I found this act disgusting as I am a fond recreational abalone diver myself,"&nbsp;he said.&nbsp;&nbsp; Scott said&nbsp;the current bag limit for each fisherman is two&nbsp;per person per day.&nbsp; A spokesperson from NSW DPI said people are encouraged to contact the body with any reports of illegal fishing through Fishers Watch on 1800 043 536 or online at the&nbsp;DPI Fisheries website. "A reward of up to $1250 may be available to anyone providing information leading to a conviction depending on the seriousness of the offence,"&nbsp;she said.&nbsp; The spokesperson said the DPI Fisheries Compliance Unit has made&nbsp;inroads into addressing illegal, unreported, unregulated (IUU) fishing in the NSW abalone fishery. "More than 5700 illegally taken abalone were seized during the 2017-18 financial year including the largest seizure of illegal abalone in 20 years,"&nbsp;she said.&nbsp; Last financial year NSW DPI seized 2560 illegally harvested abalone. "NSW DPI has seized more abalone from a number of alleged offenders this year and intend to take the offenders to court,"&nbsp;the spokesperson said.&nbsp;
